Gravity Does the Work
Take the gray reservoir and fill it up with water from any source — lake, stream, faucet, etc. After filling, hang the gray bag from a tree, the back of your pack, or simply hold it up with your hand. The color-coded system (grey goes with grey, blue goes with blue) makes filtering easy. Just connect the tube into the gray reservoir and clip the other tube end into the grey end of the Point ONE filter.
Start filtering water into either the blue reservoir (included in two-bag system) or directly into another container, and you’ll have 2 liters of fresh, clean water in about 90 seconds — ready to drink, cook with, or fill water bottles.
With the two-bag system, you can even use the blue reservoir as a hydration pack with the included drinking tube and a bite valve (sold separately).
0.1 MICRON ABSOLUTE FILTRATION
Our water filters contain a high number of tiny ‘U’ shaped hollow fiber micro-tubes that trap contaminants while allowing decontaminated water to freely pass through at a high flow rate — eliminating the need to store water and reducing the possibility of water contamination after the filtration process.
The Sawyer Point ONE (the filtering mechanism for the Gravity Filtering System) is certified for 0.1 micron filtration, meaning there is no pore size larger than 0.1 micron in size. This makes it impossible for harmful bacteria (like salmonella), protozoa, or cysts like E. coli, Giardia, Vibrio cholerae, and Salmonella typhi to pass through the filter.
All Sawyer water filters meet or exceed Environmental Protection Agency (EPA) recommended removal rates.
A LIFETIME OF CLEAN WATER
The Point ONE’s filtering membranes are sturdy enough to withstand backwashing using the included syringe, restoring up to 98.5% of the filter’s flow rate.
The Point ONE can be cleaned and reused almost indefinitely with no expensive cartridges to replace… ever. We recommend backwashing and sanitizing the filter after every outing for optimized use.
Fully field maintainable, the Gravity Filtering System includes a faucet adapter for a more thorough backwash when you get back home.
